THE MARK OF THE BEAST.

A sudden quick cry broke from Ravenspur's lips. He fairly staggered back, his white face was given over to a look of peculiar horror. Then, as he became aware of the curious glances of his companion he made a great effort to regain his self-control.

"I--I don't understand," he stammered. "A stiletto made of glass! A long, slender blade like an exaggerated needle, I presume. Yet, now I come to think of it, I recollect that, when I was painting a 'Borgia' subject once, my costume dealer spoke of one of those Corsican daggers. I did not take much interest in the conversation at the time. And so you have an idea that this is the way in which my poor friend met his death?"

Ravenspur was speaking quietly and easily now. He had altogether regained control of himself save for an occasional twitching of his lips. He paced up and down the room thoughtfully for some time, utterly unconscious of Dallas' sharp scrutiny.

"I suppose there is nothing more you have to tell me?" he said at length. "This is evidently going to be one of those crimes which thrill a whole community for a week, and then are never heard of again. Still, if there is anything I can do for you, pray do not hesitate to ask for my assistance. I suppose we can do no more till after the inquest is over?"

Without waiting for any reply from his companion Ravenspur quitted the room, and went back to his brougham. He threw himself into a corner, and pulled his hat over his eyes. For a long time he sat there immersed in deep and painful thought, and utterly unconscious of his surroundings. Even when the brougham pulled up in Park Lane he made no attempt to dismount till the footman opened the door and addressed him by name.

"I--I beg your pardon, Walters," he said, "this terrible business prevents my thinking about anything else. I am going into my own room now, and I am not to be disturbed by anybody. If I am dining out tonight, tell Mr. Ford to write and cancel the engagement. Oh, here is Ford himself."

The neat, clean-shaven secretary came forward.

"Your lordship seems to have forgotten," he said. "You are giving a dinner here tonight yourself. You gave orders especially to arrange it, because you were anxious for some of the Royal Academicians to meet the young Polish artist----"

"I had clean forgotten it," Ravenspur said, with something like a groan. "Entertaining people tonight will be like dancing in fetters. Still, I must make the best of it, for I should not like that talented young foreigner to be disappointed. In the meantime, I am not at home to anybody."
